Specification of Letters Patent.

Patented May 26, 1914i.

Application filed April 2, 1912. Serial No. 688,071.

ments in gas producers, the primary object of the invention being the provision of a novel form of reverse draft gas producer in which a clean and pure dry gas can be obtained from lignite or low grade fuel, and especially adapted for use in connection with explosive engines.

A further object of the present invention is the production of a gas producer in which the grates are placed at such an angle as to permit the gravity feed of the clean coal or lignite at the upper end thereof, the grates being provided with means for rocking the same so as to regulate a slow or fast feed of the coal over the grates, the chambered portion under the grate being divided into an upper air admitting chamber and a lower gas chamber, whereby the air is admitted through the unconsumed coal within the retort or combustion chamber of the producer and carried downwardly or in reverse direction to the ordinary draft to cause the impure gas at first produced to pass through the burning coals before entering the gas chamber, such action burning or cleaning the gas of impurities, such as tar, before the same is finally cooled and permitted to enter an explosive engine.

A still further object of the present invention is a novel form of coal feeding means in connection with the reverse draft gas producer, whereby the lump coal is precipitated to the bottom or grate portion with the finer particles thereupon, so that the said finer particles will not sift through the grate unduly, but be acted upon with the lump coal so that the maximum amount of gas is ob taincd from both the lump and dust coal.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure l is a vertical central sectional view through the complete gas producer. Fig. 2 is a detail view of one end of one of the grate bars.

Referring to the drawings, the numeral 1 designates the main cylinder or casing of the producer which is disposed and supported upon the main support 2 and the cylindrical support 3, which forms an ash pit for the gas chamber, so that the axial line of the casing 1 will be disposed at an angle of approximately with relation to the base of the apparatus.

The lower end of the casing l is sealed by a cap or cover 4, which with the lower partition 5 provides the ash pit or chamber 6 of the producer; The partition 5 in the upper portion thereof, is provided with the clinker or ash outlet 7, whereby the residue from the gas producing lignite, or other carbonaceous material, is precipitated into the ash pit or chamber 6. Formed between the partition 5 and the projecting rim 8 on the upper end of the casing 1, is the main combustion chamber 9 of the producer, the upper dome of which is lined as at 10 with fire brick to retain the heat within such portion during the production of the gas.

The partitions 5, 12 and 13 provide supports for the respective grate bar mounting rods 14, 15, 16 and 17, which have receptacles for the trunnions 18 of the longitudinally disposed grate bars 19, said rate bars 19 being disposed so that upper faces thereof constitute the lower wall of the combustion chamber 9 and are disposed at an angle of substantially 4:5 to the base of the apparatus.

In order to prevent the coal, clinkcrs or ashes from affecting the ournal portions of the respective grate bars, the plates 20, 21 and 22 are disposed to fit thereover, as clearly shown in Fig. l, and to further assist the said grate bars in the proper selffeeding of the coal downwardly through the combustion chamber, as shown in Fig. 1. The coal first acted upon will be above the grate bars at the upper portion of the co1n bustion chamber or above the air admitting chamber 23, the air being admitted or drawn through the opening 27 in the casing 1 and following the direction of the arrows as shown in Fig. 1, between the grate bars and through the body of coal over the intermediate plate 20 and finally to the grate bars above the gas chamber 2%, through the coal or lignite that is being consumed by the flames in the lower portion of the producer and finally passing out of the outlet conduit 26, from where the may be conducted to a cooling chamber and finally to the explosive engine.

In order to remove any clinkers or dust that may accumulate in the air chamber 23,

a removable cap 25 is disposed to c ntrol an outlet at the lower portion of said chamber as shown in Fig. 1. The supporting pipe 3 is also disposed to be in communication uith the lower end of the gas chamber 24:, so that any ashes or dust that may collect in such chamber will be precipitated in the ash pit 3 and be removed as desired.

Disposed above the casing 1 and having its outlet at the upper end of the combustion chamber 9, is a feeding hopper 28, which is so shaped that the larger lumps of coal, lignite or other carbonaceous material, will assume the position as shown in Fig. 1, so that the lumps or larger particles will be fed directly to the grate bars 19 with the finer particles thereover, such lumps providing a means to prevent the escape of the finer particles into the air chamber or the gas chamber before the proper extraction of the gas therefrom. In order to assist in this operation, the main feeding hopper 29 is disposed as shown in Fig. 1, so that its outlet 30 which is controlled by any form of shut ofi valve 31, will feed the carbonaceous material downwardly. The outlet to the hopper 29 is so positioned that a line drawn from the center thereof and a perpendicular line drawn through the center of the hopper 29 and with the base of the apparatus will enter or intersect the upper end of the com bustion chamber 9 above the center line thereof, this providing a means, as before stated, whereby the larger lumps of the carbonaceous material will assume the position as shown in Fig. 1. In order to operate the cut ofi valve 31, the actuating mechanism 32 is provided.

During the operation of the apparatus it is desirable that the bars 19 be properly rocked or shaken so as to precipitate the clinkers through the outlet 7 and at the same time loosen up the carbonaceous material within the combustion chamber 9 to secure a better circulation of the air from the chamber 23 through the mass of carbonaceous material and finally into the gas chamber 24:, is provided. In order to do this, the respective sets of bars 19 of the respective chambers 23 and 2a, are connected by means of the lugs 33 to a connecting bar which eX- tends through one side of the casing 1, to be manipulated or slid by hand.

From the foregoing description taken in connection with the drawings, it is evident that with the producer designed according to the present invention, that a uniform grade or quality of gas throughout the entire period of operation of the producer is the resultant, and that the fire is in no way disturbed as there is no necessity for the removal of clinkers by the running of a poker or slicing bar therethrough, as the simple manipulation of the grate bars by the bars at combined with the peculiar positioning or angle of the bars, will permit the fire to work down by gravity to bring all the noncombustible matter through the opening 7 into the ash pit at the lower end of the casing 1. By this means there will be no waste of fuel as the same will be completely consumed upon the lower grate surfaces above the chamber 24%, thus permitting the production of gas of a maximum degree from the carbonaceous material fed in at the upper end of the combustion chamber 9. By bringing the fresh air in through the air chamber and finally through the initially fed carbonaceous material, which is heated within the combustion chamber 9, the impure gas is drawn down in the reverse direction to natural tendency of the flow of the gas, and through the burning carbonaceous material so that the tar and other impurities are removed therefrom before the admission of the pure gas into the air chamber 24 and out of the outlet 26 to the explosiVeengine.

By feeding the carbonaceous material at the upper end of the combustion chamber 9 through a peculiar shaped hopper, the lump and fine particles are separated, so that the large lumps are placed directly upon the grates with the fine particles thereupon, thus providing a means whereby the waste of the material is reduced and the maximum amount of gas from a given amount of material is the resultant.

It is also evident from the construction herein shown, that the grates may be rocked more or less, to produce a slow or fast speed of the material over the grates, and thus accelerate or decrease the production of the gas as desired.

The salient feature of the present invention resides in the peculiar manner of mounting the flat grate bars 19 in position, it being noted that the grate bars are disposed longitudinally of the easing between the partitions 5 and 12, and between the partition 12 and the upper end of the casing. The ends of the grate bars are provided with the trunnions adjoining their upper edges, which trunnions are journaled to the said partitions and the upper end of the casing, the plates 20, 21, and 22 forming angular lips carried by the respective partitions 12 and 5, and by the upper end of the casing, in order that the end portions of the upper edges of the grate bars will fit snugly under the said lips to permit the fuel to gravitate readily over the said lips and grate bars.

By the peculiar arrangement of the air chamber which causes the air to be fed through the initially fed carbonaceous material within the upper end of the combustion chamber, the tar is extracted from the gas by passage through the burning carbonaceous material at the lower end of the producer or combustion chamber so that with an apparatus of this character the usual tar extractor is dispensed with, the gas being purified by passage directly through the burning material before admission to the gas chamber and to the explosive engine.

What is claimed is:

In a gas producer, an inclined casing having a lower partition, and an upstanding partition intermediate the aforesaid partition and the upper end of the casing, angular lips carried by the upper edge of the second mentioned partition and by the upper end or the casing and the first mentioned partition, the upper end of the casing and the first mentioned partition having openings above the respective lips, two sets of flat grate bars disposed longitudinally of the casing between the said partitions and between the second mentioned partition and the upper end of the casing, respectively, the ends of the grate bars having trunnions adjoining their upper edges, the trunnions be ing journaled to the said partitions and end of the casing, the end portions of the upper edges of the grate bars fitting snugly under said lips, the lower edges of the grate bars depending and having depending lugs, and shaker bars slidable through one side of the casing and pivoted to the lugs of the respective sets of grate bars, the casing having an air inlet and a gas outlet communicating with the respective air chambers below the two sets of grate bars.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
